3HM1

3HM1 Limit Switches are known as a Snap Action type of switch. They are quick-acting mechanical switching devices used to control the position of objects and regulate the transportation of power. In some applications, they are also used as safety devices that trips and protects the system from further damage.

3HM1 Limit Switches are often used for accurate control of home appliances and industrial machines with a minimum of maintenance. They generally require no external source of power and due to their size and robust build, they can be easily and securely embedded in a tight space.

The typical features of 3HM1 Limit Switches include a body with a pushrod that is attached to the working contact and a release lever, which is connected by a connecting rod to a working mechanism. When the pushes are operated, the pushrod is released, which causes a rapid and seismic change in the switch position. The mechanism is designed so that the contact gap is adjusted when the switch is operated, allowing a greater or lesser amount of circuit contact current.

The working principle of the 3HM1 Limit Switches is dependent upon the rotation of an armature within the device. An external force must be applied to the armature to engage the switching mechanism. When the force is applied, an eccentric shape of the armature causes the contact surface to separate, breaking the contact. Depending upon the specific design, the disengaging force must be either a mechanical force or an electrical current.

The applications of 3HM1 Limit Switches are numerous. They are used extensively in the automotive and automotive aftermarket industry, as well as in other industrial applications for safety, control, and sensing applications. They are also used in home appliances and medical devices as a safety switch that trips and protects the system from further damage.

3HM1 Limit Switches are designed to be reliable, needing no maintenance and providing long service life. Their design is also usually very cost-effective, offering excellent performance and value for money.
