Honeywell SP-CO Plunger Microswitch, 3.61N Operating Force, 15A - BZ Series - BZ-2RQ181-A2
This microswitch from Honeywell is designed for on/off applications in industrial environments where the roller plunger needs to be at a 90° angle to the switch. Its case is made of a lightweight phenolic material that's highly durable and provides good insulation, making it safe to handle. This unit has a long lifespan of up to 20 million cycles, so it will last a long time and reduce the need for frequent replacement and maintenance. It has an elongated mounting hole that accepts both pins and screws, allowing for simple and versatile installation.
