Types of Switches, Buttons & Keys
Switches and buttons are the primary control interface in electronics, enabling manual or mechanical circuit actuation. Our inventory covers toggle switches, rocker switches, push buttons, DIP switches, micro switches, slide switches, rotary switches, and key-operated switches. Each type offers distinct operational behavior: toggle switches provide stable on-off positions, push buttons offer momentary action, DIP switches allow easy configuration settings, and rotary switches enable multi-position selection.
When selecting a switch for your project, consider key parameters such as contact rating (voltage and current), actuation force, mounting style (PCB, panel mount, or solder lug), IP rating for dust/water resistance, and life cycle durability. For microcontroller-based designs with Arduino or ESP32, low-current tactile or push buttons are typical, often requiring debouncing techniques. In contrast, power control circuits may need toggle or rocker switches capable of handling higher currents. Always verify the switch's electrical endurance to ensure reliable long-term operation.
Common Switch Types
- Toggle Switch: Lever-actuated, latching on/off; ideal for control panels.
- Push Button: Momentary contact; widely used for reset or start signals.
- Rocker Switch: Rocking actuator, often illuminated; common in power supply units.
- DIP Switch: PCB-mounted block of micro switches for configuration.
- Micro (Tactile) Switch: Miniature, high-precision switch used as limit sensors in robotics.
- Rotary Switch: Multi-position rotating switch; used in speed or mode selection.
If your circuit demands frequent high-current switching, choose switches with gold-plated or durable contact materials to prevent oxidation. For panel mounting, double-check the cutout dimensions and depth. High IP-rated switches (e.g., IP67) are recommended for outdoor or harsh environments to ensure longevity. Additionally, key-operated switches add a security layer, restricting operation to authorized personnel.
