An interlock switch is a safety device that protects against the tripping of electrical devices. They are available in different styles and configurations, including power-to-release and power-to-lock models. They are typically used to control a motor, such as a car engine. To select a safety interlock switch, consider the following aspects. These components play an important role in protecting against hazards. Here are some tips for choosing an interlock switch.
The main function of an interlock switch is to prevent accidents and other potentially harmful situations. In a typical safety system, a key is inserted into a slot and turns the switch on or off. The slot is usually mounted on a machine guard or door. The key fits snugly into the slot when the door is closed, preventing tampering. An interlock switch is difficult to disable without the correct key, because it performs three separate mechanical functions when inserted into a slot.
Noncontact safety interlock switches are made of plastic or chemically-resistant steel and must meet safety standards. They are made up of one or more read heads and an actuator. The actuator processes the data and transmits it to the control unit. Once the control unit recognizes the data, the safety outputs are closed. These interlock switches are usually coded and cannot be reprogrammed. For a safe operation, they should be designed with flexibility and productivity in mind.
Safety interlock switches are usually made of plastic or chemically-resistant steel. They are required to meet safety standards. They consist of a read head and actuator that process data for transmission to the control unit. If the data is recognized by the control unit, the safety outputs will be closed. Some of these safety interlock switches have an element that cannot be reprogrammed. A jumper is also necessary to connect two separate safety interlocks.
Safety interlock switches are non-contact and can be made from plastic or chemical-resistant steel. They are generally compliant with safety standards and are composed of a control unit and a read head. The control unit recognizes the transmitted information when the switch is closed. It is important to consider flexibility and productivity when designing a safety system. When a safety interlock switch is not physically connected, it is not a positive-break device.
Safety interlock switches can be either contact or non-contact. Some safety interlock switches require the use of a magnetic switch to prevent physical contact. Some of the types of safety interlocks are magnetic. A spring-operated safety is used to prevent the switch from disabling. A non-contact switch can also be installed on an assembly line or in a warehouse. The HS safety interlock switch family is available in different sizes and contact configurations.
