Description

Switch unit that can be configured to open and close contacts at the same time {A SWITCH UNIT COMPOSING NORMAL OPEN CONTACT & NORMAL CLOSE CONTACT AT THE SAME TIME}

The present invention relates to a switch unit that can be configured at the same time, the upper and the closing contact, more specifically, to improve the internal structure of the switch unit to configure the opening and closing contact at the same time on one switch unit or two The present invention relates to a switch unit that can simultaneously configure one open / close contact point to be configured at the same time.

In general, a switch for controlling an electronic circuit used in factory automation includes a button switch constituting a circuit loop using a contact only when pressed, and a select switch constituting a circuit loop using a contact only when selected. Various kinds of control switches such as select switch are widely used.

As part of the control switch component as described above, the switch unit is coupled to the fixed unit serves to electrically connect the operation unit and the switch unit.

In the conventional switch unit 6, as shown in FIGS. 1 and 2, the first and second cases 1 and 2 provided with the movable terminal 3 for the open contact or the closed contact and the fixed terminal 4 are installed therein. Combination is made, it was possible to form the opening or closing contact by the operation of the switch.

In addition, the switch unit 6 was used in combination with a fixed unit by using a fastening means such as a bolt 5.

However, the switch unit 6 as described above is configured to form only one contact point on one switch unit 6, and there is a limit to the increase of the contact point. Since the switch unit 6 had to be attached to the fixed unit and used, it was inconvenient to assemble due to an additional process and was inefficient in terms of time and cost.

In addition, the coupling means such as bolts (6) when the coupling with the fixed unit using a screwdriver was not easy to attach and detach.

The present invention was created in view of the above-described problems, and it is possible to simultaneously configure an open (NO) and a closed (NC) contact on one switch unit or to configure two open contacts at the same time, so that the contact is relatively The purpose of the present invention is to provide a switch unit that can be configured to open and close the contacts at the same time, which can be increased and the assembly process can be shortened and at the same time, the coupling means are integrally formed at the lower end to facilitate detachment and attachment. have.
