Toggle switches are special type of switchable electrical components whose purpose is to change the state of an electrical circuit when being operated. The ST21KMV2QE is a general-purpose toggle switch, designed to be suitable for any number of switching applications. This type of toggle switch features a two-step mechanism which enables it to securely switch between the off and on positions with minimal effort, and is available in a variety of actuator styles to suit diverse applications.

Design

The ST21KMV2QE toggle switch is a single-pole, single-throw switch which can be operated with minimal force. Its design incorporates a two-step mechanism which allows for a secure transition between the off and on positions. The switch’s actuator is constructed of a durable plastic which is available in a range of designs, enabling it to be easily adapted for various switching applications.

Contact Rating

The ST21KMV2QE toggle switch is rated to carry a maximum of 277 Volts AC and 5 Amps. With this wiring and rating, the switch is capable of safely switching loads of up to 1,385 Watts. This rating is suitable for most small-scale domestic and industrial applications, but should not be used for higher voltage and amperage loads.

Environmental Ratings

The ST21KMV2QE toggle switch is designed to operate reliably in both indoor and outdoor environments. It is rated to withstand temperatures from -25°C to +65°C, and is also furnished with an IP67 rating for protection against dust and liquids. The switch is also resistant to most chemicals and UV radiation, thus making it suitable for most environmental conditions.

Installation

The ST21KMV2QE toggle switch is able to be mounted in any orientation by means of its threaded mounting hole. The switch requires a panel hole of 28.7 mm in order to be fitted correctly. The switch is designed with a locking washer, ensuring a secure and reliable mounting.

Working Principle

The ST21KMV2QE toggle switch is designed to be operated with minimal force. When the switch is operated, the actuator actuates a two-step mechanism, allowing the switch to be safely switched between the off and on positions. Since the switch features a locking mechanism, it is impossible to move the switch to the on position without exerting significant force. This feature helps to avoid unintentional switching while also providing a secure connection.

Applications

The ST21KMV2QE toggle switch is suitable for a wide range of applications. Its robust design ensures reliable and durable operation in both indoor and outdoor environments, making it suitable for domestic, commercial, and industrial applications. The switch is able to be used to switch variety of loads, including motors, pumps, and lighting systems. It is also capable of switching a large number of circuits, making it ideal for applications such as controlling multiple lights in hazardous areas.
