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 doesnot hold the buttons in the depressed position. It simply prevents pushing both buttons at the same time. Table 19.301: Interlock Description Type TheType K3 interlock is mounted behind the operators. Operators not included. K3 NOTE: When ordering, add prefix 9001 to the catalog number.
