alarm monitor systems
The button structure, the LEDs and the light guide component are mounted below the flexible gasket. The flexible gasket is configured to deflect in response to a press on the button top of the button assembly. The flexible gasket has a top surface impermeable to water and edges that extend beyond sides of the button top. The edges of the flexible gasket include a first peripheral edge and a peripheral region located in proximity to the first peripheral edge. The first peripheral edge of the flexible gasket makes a water tight seal with a second edge of the opening of the front cover plate, and the peripheral region of the flexible gasket is substantially transparent to visible light. The button structure is configured to be actuated in response to the press on the button top.
