## Summary description

Eltako impulse (pulse) switch 1S S12-100-24V DC is a single-pole switching device rated at 16 A for control circuits operating on 24 V DC. Designed for installation in distribution boards, it provides electrically controlled on/off switching via pulse inputs. Suitable for lighting and motor control, remote switching and automation tasks where a compact DIN-rail mounted impulse relay is required.

## Long description

Eltako 1S 16A 24V DC impulse switch S12-100-24V DC is a single-pole, DIN-rail mounted switching module intended for control circuits operating from a 24 V DC supply. The device accepts pulse control inputs to change its output state, providing on/off switching for connected loads up to 16 A. Its compact format and electrical isolation between input and output make it suitable for installation in distribution boards where space-efficient, electrically driven switching is required.
Advantages
The impulse switch provides reliable pulse-controlled switching with a rated switching current of 16 A and is designed for 24 V DC control systems. Its single-pole contact reduces wiring complexity for simple on/off applications, and the DIN-rail housing ensures secure mounting in electrical cabinets. The electrical design isolates the control input from the switched circuit, allowing integration with a wide range of control devices and automation systems.
Suitable for
Lighting circuits requiring remote or centralized switching
Control of small motors and actuators within 16 A limits
Automation and remote switching tasks in low-voltage DC systems
Space-limited distribution boards where DIN-rail mounting is needed
Key specifications
Contact configuration: single-pole switch
Rated switching current: 16 A
Control voltage: 24 V DC
Mounting: DIN-rail compatible enclosure
Control type: pulse (impulse) input for toggle switching
Intended application: electrical on/off control in DC circuits
How to use
Install the impulse switch on a standard DIN-rail inside the distribution board and connect the load to the switching contact according to the circuit diagram. Apply a 24 V DC supply to the control input; each pulse signal toggles the output state between on and off. Ensure the connected load does not exceed the 16 A rating and observe correct polarity and separation between control and load circuits where required. Follow local wiring regulations and disconnect power before installation or maintenance.
Usage recommendations
Use the device for centralized or remote switching within low-voltage DC installations and combine it with appropriate protective devices such as fuses or circuit breakers sized for the load. Verify compatibility with control pushbuttons, sensors or automation outputs that provide 24 V DC pulse signals. For applications near the rated current, allow for adequate thermal conditions and follow manufacturer installation instructions for reliable operation.
