Class 9001 / Refer to Catalog 9001CT1103

Interlock for Type K and SK Operators

For mechanically interlocking two push buttons so that only one button can be depressed

at a time. A Type K3 attachment is furnished with the 9001 KR11, KR12, SKR11,

SKR12, SKRU1 and SKRU11 operators. However, these are maintained operators and

the K3 interlock serves to release one of the buttons when the other is depressed. When

used with momentary contact buttons, the K3 interlock does not hold the buttons in the

depressed position. It simply prevents pushing both buttons at the same time.
