Gracias a estas caracterlsticas, se obtiene un sistema que ofrece una mayor resistencia en la zona de contacto frente a la solucion de la tecnica actual, siendo una solucion economica y sencilla de aplicar dado que solamente debe insertarse una arandela metalica en la fase de montaje del dispositivo. El hecho de que sea de material metalica permite soportar un valor de fuerza mas grande que en el caso de tratarse de material plastico, y al mismo tiempo, incrementar la vida util del dispositivo interruptor. Esta arandela, por lo tanto, permite el deslizamiento forzado del soporte en situaciones predeterminadas en donde el pedal vinculado al interruptor realiza una carrera mayor de la prevista, y con un valor de fuerza superior, por ejemplo a 160 N.Thanks to these characteristics, a system is obtained that offers greater resistance in the contact area compared to the solution of the current technique, being an economical and simple solution to apply since only one metal washer should be inserted in the assembly phase of the device. The fact that it is made of metallic material allows it to withstand a greater force value than in the case of plastic material, and at the same time, increase the useful life of the switch device. This washer, therefore, allows forced sliding of the support in predetermined situations where the pedal linked to the switch makes a greater stroke than expected, and with a higher force value, for example at 160 N.

Otras caracterlsticas y ventajas del dispositivo interruptor de pedal objeto de la presente invention resultaran evidentes a partir de la description de una realization preferida, pero no exclusiva, que se ilustra a modo de ejemplo no limitativo en los dibujos que se acompanan, en los cuales:Other features and advantages of the pedal switch device object of the present invention will be apparent from the description of a preferred, but not exclusive, embodiment which is illustrated by way of non-limiting example in the accompanying drawings, in which:
