- Guaranteed reliability for 1,000,000 switching cycles, resistant in environments with temperatures between -25°C and +70°C
- Quick installation with panel mounting and a standard 43mm diameter cutout
- IP42 protection after mounting against dust and accidental splashes
- Robust construction from plastic and metal with screw clamp terminals for secure connections
How it works and how to install it
Operation
The rotary selector only actuates the electrical circuit as long as it is held in positions 1 or 2. Upon release, it automatically returns to position 0, interrupting the power supply. This cam mechanism provides precise temporary control, ideal for jogging operations or equipment testing.
Installation
Requires a 43mm circular cutout in the electrical panel. It is fixed by tightening it to the front of the panel, then the cables are connected to the screw terminals at the back. No special tools are needed — a socket wrench and a screwdriver are sufficient.
Frequently asked questions
How long does it stay active after I turn the selector?
The circuit remains active only as long as you hold the selector in position 1 or 2. When you release the button, it automatically returns to position 0 and cuts off the power.
Can I use this switch for three-phase electric motors?
Yes, it supports voltages up to 440V AC and a thermal rated current of 20A, making it compatible with most industrial motors and machinery in the AC-15 configuration.
Is it resistant to humidity or dust in the workshop?
After proper panel mounting, it offers IP42 protection — sufficient for normal industrial environments. For direct exposure to water or intense dust, an additional enclosure is required.
