Features/Applications
Features/Applications These contact blocks are designed for use on ALL REES push button operators and selector switches as shown on the preceding pages. The mechanical life of these devices is 1,000,000 operations. Each captive terminal on the contact block will accept (2) # 14 AWG stranded wires and the contacts are gold plated to eliminate high resistance tarnishing.
The 52702 block consists of a B block (50702) attached to an adapter. This adapter Opens the NC contact of the B block Upon Removal from the switch operator. The OUR action provides an added level of security for instances where a NC block may be removed from the operator.
