22mm round metal actuator Heavy-duty selector switch 3 positions (I-O-II) Left side latching Right side momentary Solvent-resistant

The Siemens 3SB3500-2UA11 is a 22mm round metal actuator designed as a heavy-duty selector switch. It features three positions (I-O-II) with a specific operation mode: latching on the left (I to O) and momentary contact on the right (O to II). This switch is non-illuminated, solvent-resistant, and includes a black holder.

This unique selector switch configuration is useful for applications where the left position requires a maintained state for safety or operational reasons, while the right position is for a temporary function. Its robust, solvent-resistant design is suitable for harsh industrial environments.

What is the specific operational behavior of the Siemens 3SB3500-2UA11 selector switch?
The Siemens 3SB3500-2UA11 operates with latching on the left side (positions I to O) and momentary contact on the right side (position O to II). This means the left selection stays engaged, while the right selection only activates when actuated.
