MICRO SWITCH Premium Large Basic Switches 6AS SERIES - PREMIUM LARGE SNAP-ACTION TANDEM SWITCH ASSEMBLY The MICRO SWITCH 6AS Series consists of two large premium BZ/BA/BM/BE snap-action switches ganged together and actuated by a single actuator. Operating characteristics are dependent upon the type of individual switches and actuators chosen. Field adjustable oper- ating point on one or both basic switches. Solder, A2, and T-type terminations available, along with straight, roller, and leaf levers. Mounting holes accept pins or screws of 3,53 mm [0.139 in] diameter. Often used for boiler controls or anywhere two circuits need to be controlled by one actuator.

MICRO SWITCH Premium Large Basic Switches OPERATING CHARACTERISTICS Table 3. Operating Characteristic Definitions Characteristic Description Differential Travel-DT Plunger or actuator travel from point where contacts “snap-over” to point where they “snap-back.” Free Position-FP Position of switch plunger or actuator when no external force is applied. Full Overtravel Force Force required to attain full overtravel of actuator. Position of switch plunger or actuator at which point contacts snap from normal to operated position. With flexible or adjustable actuators, the operating position is measured from the end of the lever or Operating Position-OP its maximum length. Location of operating position measurement shown on mounting dimension drawings. Amount of force applied to switch plunger or actuator to cause the contact “snap-over.” Note in the case Operating Force-OF of adjustable actuators, the force is measured from the maximum length position of the lever. Overtravel-OT Plunger or actuator travel safely available beyond operating position. Pretravel-PT Distance or angle traveled in moving plunger or actuator from free position to operating position. Amount of force still applied to switch plunger or actuator at the moment contacts snap from operated Release Force-RF position to non-operated position. Total Travel Distance from actuator free position to overtravel limit position. Sensing and Internet of Things 15
