What type of switch must an Electrical Worker use when installing a recessed contact under a threshold?

A wide gap switch is designed to operate effectively in scenarios where there may be a specific distance requirement for its actuation, making it ideal for use in recessed contacts under a threshold. The wide gap feature allows for the necessary space between the switch and the actuator, accommodating variations in the environment, such as changes in flooring height or slight misalignments caused by thermal expansion and contraction. Using a wide gap switch in this situation minimizes the risk of misfires or failure to activate due to inadequate proximity between the switch and the actuator, thereby ensuring reliable operation and adherence to safety standards. This characteristic makes it particularly suitable for environments where precise alignment may be challenging.
