Real-World Testing: Putting Sierra International TG19520 Tip Lit Toggle Switch On Off On Dpdt to the Test
First Use Experience
My primary testing grounds for this tip-lit toggle switch were the electrical panels of my sailboat, specifically integrated into a custom-built accessory board designed to manage auxiliary lighting and pump systems. This environment is unforgiving, characterized by constant vibration, high humidity, and the occasional splash of saltwater. Installation was straightforward, with the brass blade terminals providing a secure connection for my crimped wires. The DPDT On-Off-On configuration was crucial for my dual-circuit needs, allowing for flexible control of both primary and auxiliary functions for accessories like a bilge blower and its backup pump.
During initial use, the tip lighting feature proved immediately useful. When the boat’s panel lights were on, the tip of the switch glowed a soft white, indicating its position in neutral or ‘off’ state. Flipping the switch to either ‘on’ position transformed the tip’s illumination to a clear, distinct red, offering an unambiguous visual confirmation of active circuits. This was a significant upgrade from my old, unlit switches, where guessing the state of a circuit was a common occurrence. The action of the switch itself is satisfyingly crisp, with distinct detents for each position, preventing accidental engagement or disengagement.
