<p>PURPOSE:To reduce the size and cost, and improve the design freedom degree for an underwater housing by making a switching action of a switch main body through an actuation pin set movable in an operation button action direction. CONSTITUTION:For a pushbutton switch S, a tact switch (switch main body) 5 is disposed in a space formed of a lower housing 1 and an upper housing 3. An actuation pin 11 is applied to and disposed at an operation button 5A of the switch 5, and the pin 11 is set movable in the action direction of the button 5A. A space 7 for protection to a pressure, and a rubber material 9 for protection to water are disposed between both housings 1, 3, and an operation part 13 is provided on the upper housing 3 side of the rubber material 9. When the part 13 is pushed, therefore, the material 9 is pushed to be deformed, and the pun 11 pushes the button 5A, so the switch makes a switching action. The switch can thus be compact, the reliability can be maintained for a long period, and a manufacturing cost can be reduced.</p> |
