2 Position 1NO and 1NC Heavy Duty Keyswitch

Industrial Grade Heavy Duty Key Switch

A 2 Position Heavy Duty Keyswitch acts as a secure, industrial-grade, and durable on/off switch for control applications, requiring a key for activation to prevent accidental or unauthorized use. The "1NO1NC" configuration means it has one Normally Open (NO) contact and one Normally Closed (NC) contact, allowing it to control two separate circuits or components simultaneously while the key is turned between its two positions, making it a versatile choice for machinery and equipment panels.
