The 164J2A22 is a 2-position keylock switch from the Command Series, featuring 2 normally open and 2 normally closed contacts with maintained key-pull-left action. This industrial control switch is rated for 0.4 VA at 20 VDC or peak AC, and 5 A at 250 VAC or 24 VDC resistive loads, with an initial contact resistance of 20 milliohms maximum and insulation resistance of 100 megohms minimum. The switch provides a dielectric strength of 1,500 VAC and is designed for 100,000 operations at rated current, with an operating temperature range of -20°C to +70°C. The 164J2A22 is commonly used in industrial control panels, machinery interlocks, and access control systems where reliable keyed switching and maintained contact operation are required.
