Introduction
Switches are foundational components in electronic systems, enabling control over circuits by interrupting or redirecting electrical currents. At Zenka Europe, we specialize in delivering precision-engineered switches tailored to industries like industrial automation, medical devices, and automotive systems. Below, we break down switch types, their uses, and selection criteria.
A switch is an electromechanical device that opens or closes a circuit to control power flow, signal transmission, or system activation. From household appliances to aerospace systems, switches ensure seamless functionality across applications.
1. Toggle Switches
Toggle switches are manual control devices that allow users to turn a circuit on or off by flipping a lever, button, or slider between two or more positions. They are commonly used for binary operations like switching lights or powering devices.

Top Applications
2. Snap Action/Limit Switches
Snap action switches, also known as limit switches, are electromechanical devices that detect the presence or absence of an object and instantly open or close a circuit when the actuator is triggered. They are commonly used in industrial machinery, automation, and safety systems to control or limit movement based on physical contact.
Micro-precision springs activate at 0.1-2mm travel distances. Stainless steel rollers withstand 10 million cycles. UL 61058-1 certified for safety systems.
Critical Use Cases
3. Slide Switches
Slide switches are small, manual control devices that allow users to open or close an electrical circuit by sliding a button or lever back and forth along a linear path. They are commonly used in compact electronic devices for functions like power control or mode selection.
3-5mm profile SMD/PTH designs with gold-plated contacts (≤5mΩ resistance). Operating force: 1.5-3N.
Deployment Scenarios
4. Pushbutton Switches
Pushbutton switches are momentary or latching electrical switches that activate when pressed, typically returning to their original position when released (momentary) or staying in position until pressed again (latching). They are widely used in devices like keyboards, industrial controls, and appliances for initiating or interrupting circuits.
12mm diameter anti-vandal switches (316 stainless steel) with 50N actuation force. Illuminated variants feature 360° light guides.
Sector-Specific Solutions
5. Selector Switches
Selector switches are rotary or lever-based switches that allow users to choose between multiple circuit options by turning a knob or moving a lever to different positions. They are commonly used in control panels to select modes, functions, or settings, such as in machinery, HVAC systems, or electronic equipment.
4-12 position rotary cam mechanisms with detent feedback. DIN 43620 standard compliance for industrial panels.
Industrial Applications
6. Thumbwheel Switches
Thumbwheel switches are compact rotary switches operated by rolling a wheel with a thumb or finger to select numerical or positional values, often used for setting parameters like addresses, data inputs, or configurations in electronic devices and control systems.
BCD-coded 10-position wheels with optical encoding for 0-9999 input ranges. IP65 dust/water protection.
Key Implementations
7. Tactile Switches
Tactile switches are small, momentary pushbutton switches that provide physical feedback (a "click" sensation) when pressed, typically used for user input in electronic devices like keyboards, remote controls, and circuit boards. They are designed for quick and precise actuation.
4mm dome switches with 160gf actuation force and 0.2mm travel. Rated for 100,000+ cycles.
Consumer & Medical Uses
8. Rotary Switches
Rotary switches are electromechanical devices that rotate to select between multiple contacts or circuits, often used for functions like voltage selection, mode switching, or control settings in appliances, industrial equipment, and audio devices. Their knob-based design allows precise multi-position control.
24-position ceramic wafer contacts handling 5A at 250VAC. MIL-PRF-39016 military specifications.
Critical Systems
9. Rocker Switches
Rocker switches are paddle-shaped switches that pivot on a central point, allowing users to turn a circuit on or off by pressing one side down. They are commonly used in household appliances, automotive controls, and lighting systems for simple and intuitive operation.
Dual-color LED backlighting with ±0.5mm actuation tolerance. 16A/250VAC rating for white goods.
Common Deployments
10. Pushbutton Switches
Pushbutton switches are momentary or latching electrical switches that activate when pressed, typically returning to their original position when released (momentary) or staying in position until pressed again (latching). They are widely used in devices like keyboards, industrial controls, and appliances for initiating or interrupting circuits.
12-48V DC operation with 10-300mA sink/source capability. -40°C to 125°C operating range.
Harsh Environment Uses
11. Programmable Display Switches
Programmable display switches integrate a visual display (such as an LCD or LED screen) with a switch, allowing users to program and view specific settings or functions directly on the device. They are commonly used in advanced control systems, automation, and industrial equipment for customizable and user-friendly operation.
128x64 pixel OLEDs with capacitive touch. Modbus RTU protocol support for PLC integration.
Industry 4.0 Applications
12. Navigation/Joystick Switches
Navigation/joystick switches are multi-directional input devices that allow users to control movement or selection by tilting a joystick in various directions, often including a central pushbutton for additional functionality. They are commonly used in gaming controllers, robotics, and industrial machinery for precise directional control.

Precision Systems
13. Magnetic/Reed Switches
Magnetic or reed switches are electromechanical devices that open or close a circuit in response to the presence or absence of a magnetic field, utilizing a pair of ferrous metal contacts enclosed in a glass tube. They are commonly used in security systems, sensors, and proximity detection applications due to their reliability and contactless operation.
0.5-50 Gauss activation thresholds. Hermetically sealed glass tubes with 10^8 operation lifespan.
Security & Automation
14. Keypad Switches
