<p>PURPOSE:To use a panel as a push button, by providing L-shaped projected sections at the upper and lower edges of the front face of a tray, a panel equipped with L-shaped projected sections which are slidably engaged with the L-shaped projected sections of the tray, and a switch between the tray and panel. CONSTITUTION:Under normal conditions, a panel 2 is pushed forward by means of the returning force of a switch 4 and the L-shaped projected sections 10 and 11 at the upper and lower edges of the panel 2 and the L-shaped projected sections 3 and 9 provided at the upper and lower edges of a parts 1b contact. When the lower surface of the panel 2 indicated by the arrow B is pushed under this condition, the L-shaped projected section 10 at the upper edge of the panel 2 contacts the upper L-shaped projected section 8 of the parts 1b and the panel 2 rotates around the contacting position and turns on the switch 4. When the upper face of the panel 2 indicated by arrow A is pushed, on the contrary, the lower projected section 11 of the panel 2 contacts the lower projected section 9 of the parts 1b and the panel 2 rotates around the contacting position and turns on the switch 4.</p> |
