125μ thick conductive film “High Beam BS12”
(Toray), and using ultraviolet curing resist ink "ED-115" (Toyobo), print on the conductive thin film surface of each film by silk screen printing method, and apply ultraviolet irradiation device (Oak). A resist layer for fixed contacts is formed on one film, and a resist layer for movable contacts is formed on the other film. was formed. Thereafter, etching treatment was performed using a 5% aqueous solution of hydrochloric acid, and the resist layer was peeled off using a 2% sodium hydroxide solution to form a transparent fixed contact and a movable contact. Next, using silver paste ink "427SS" (Nippon Acheson) and graphite paste ink "423SS" (Nippon Acheson), circuits were applied to the above-mentioned film with transparent fixed contacts and film with transparent movable contacts, respectively. Both the pattern and the connector lead portion were printed using a silk screen printing method, and dried and cured at a temperature of 120° C. for 20 minutes. Ultraviolet curable ink "#9051" (Seiko Advance) was applied approximately in the center of the transparent fixed contact of the fixed contact support plate thus formed and on both left and right sides of the fixed contact.
5mm by silk screen printing method using
A small protrusion-shaped spacer with a diameter of 0.5 mm was printed with a pitch, and it was exposed and cured under the same conditions using the above-mentioned ultraviolet irradiation device. In addition, on the outer surface of the movable contact support plate, a polyester ink "GAP Medium" (Seiko Advance) containing 5% hardening agent was printed as an undercoat by silk screen printing using a Tetron 250 mesh plate. It was dried and cured at 80°C for 30 minutes. On top of this, a polyester ultraviolet curable ink "#9051-S" (Seiko Advance) containing 3.0% by weight of microsilica was printed by silk screen printing using a Tetron 200 mesh plate, and the above ultraviolet irradiation device was used to print. exposed to light and cured under the same conditions, and the thickness
A 10μ thick cured resin layer was formed. The fixed contact support plate and the movable contact support plate were integrated with double-sided adhesive tape to obtain a transparent touch switch. The obtained transparent touch switch had excellent wear resistance and did not reflect external light. Effects of the invention The transparent touch switch of the invention has excellent wear resistance and does not get scratched even when the switch is pressed many times. This transparent touch switch
If used by setting it on the front seat of a CRT, there will be no glare from the lighting, and there will be no erroneous operation caused by it.
