The 1LS56 from Zettler electronics is a rugged, short-travel snap action switch designed to provide many years of reliable service in harsh, industrial applications. The 1LS56 is ideal for use with switches, pushbuttons, actuators, and emergency stop switches. It is composed of two parts, the actuator and the body, each of which is constructed of zinc-plated steel. The body is mounted to the wall and is designed to protect the actuator from shock, vibration and electro-magnetic interference.

The 1LS56\'s working principle is based on a simple mechanical concept. When the button is depressed, a tension spring inside the switch is displaced, stretching the spring to its maximum tension. When the button is released, the force of the spring, together with the pressure from the actuator, cause the switch to snap into place. This snap action creates an audible click that can be heard when a switch is operated, and provides visual and tactile feedback for the user.

The 1LS56 has an adjustable operating force, making it suitable for use in a wide range of applications. In a normal on/off application, the switch can be adjusted to turn on at a low force and turn off at a high force, ensuring reliable operation in the long term. In an emergency stop/safety switch application, the higher force setting can be used to ensure the switch cannot be inadvertently actuated in the event of an emergency.

The 1LS56 is rated to operate at 250VAC/DC and 10A, making it suitable for a variety of power applications. It is available with various actuator types, including roller lever, plunger, and mushroom actuators, enabling users to select the most suitable option for their application. Additionally, the switch is UL and CSA certified.

Overall, the 1LS56 is a reliable, cost-effective snap action switch suitable for a variety of harsh, industrial applications. Its adjustable operating force, wide operating voltage range, and UL/CSA certifications make it an ideal choice for applications where reliability is critical.
