Eltako S12-110-24VDC impulsschakelaar 1NO+1NC 16A DIN-rail 21110055

The Eltako S12-110-24VDC stands out as a compact impulse switch that combines one normally open and one normally closed contact in a single module, enabling both switching and disconnect functions from one device. Its 24V DC control voltage makes it suitable for low-voltage control circuits, while the 16A contact rating handles substantial loads.

Highlights

• 1 NO + 1 NC contact configuration for versatile switching
• 16 A rated switching current at 250V AC
• DIN rail mounting with only 1 module width (18 mm)
• Low standby power consumption of 0.03 W
• High mechanical life of over 10 million operations

In daily use

This impulse switch is ideal for lighting control, staircase timers, and general automation where a maintained contact state is required without continuous coil power. The AgSnO2 contacts ensure reliable switching of incandescent, halogen, fluorescent, and LED loads within specified limits. Its compact size saves space in distribution boards.
