Once released, the circuit opens again. This makes them ideal for triggers, resets, doorbells, or any application where you need a temporary signal rather than a latching ON\/OFF state.\u003c\/p\u003e\n\u003ch4\u003eQ: How waterproof are the PBS-33B switches?\u003c\/h4\u003e\n\u003cp\u003eA: These switches feature a waterproof design that protects the internal contacts from moisture and light splashing, making them suitable for outdoor enclosures, wet environments, or applications where occasional exposure to water is possible.
