For fast action electronics there are Grey coded versions with one a one-bit change, eliminating electronic problems between positions. The usual options of torque, stopped positions and sealing are available.

SPRING RETURN
All of WASP rotary switches have the option of being fitted with a spring return facility. This can be fitted at either end of the operation and allows for a test of secure position.
PULL-TO-TURN
The Pull-to-Turn addition is available on the DB, DC, and DR range of switches and allows for the design such that one or both end positions can only be entered if the spindle is pulled before turning. This gives a totally secure position that cannot be entered accidentally. This is available as a panel and spindle sealed switch.
PUSH BUTTON
On all ranges WASP can provide a Push Button facility that can be operated in each position by pushing the spindle. This design is achieved with a complete panel and spindle seal.
