Honeywell Pin Plunger Micro Switch, Quick Connect Terminal, 25 A, SP-CO

This microswitch from Honeywell has a snap-action mechanism that opens and closes an electrical connection. It's a smaller version of a limit switch that's used to control mechanical operations. The switch is suitable for use with low-level currents of up to 25A. It has a high-strength thermoplastic housing that keeps the switch mechanism protected against wear and impact in heavy-duty industrial applications. The vertical movement of the pin plunger makes this switch a good choice for short, controlled machine movements.

• Silver plating on contacts is resistant to rust to ensure a high-quality connection
• Wide operating temperature range of -40°C to +85°C for use in demanding environments
• Robust mechanical lifespan of up to 10 million cycles for long-lasting use

• Vending machines
• Emergency stop controls
• Door releases
• Water heaters
• Domestic appliances

Pin plunger-style actuators have a plunger mechanism that's pushed down to create a reciprocating motion that triggers the microswitch.

This microswitch requires 2.21N (newtons) of operating force and 0.2N of release force, making it sensitive for quick response times.
