Due to the necessity of import substitution, we have designed our own connector (Zenitco connector). All of our products are currently switching to it. All the shortcomings that the previously used connectors had were taken into account and eliminated. The Zenitco connector is very reliable: the contacts are positioned in such a way that in case of an incorrect installation attempt, they cannot be bent and damaged. Only when two trapeziums are connected to each other, the connector plugs in easily.

We continue to provide support for products on previous connectors, as well as the sale of remote switches for such products. All new products will be with switches with Zenitco connector. The ability to control two products simultaneously by KV-D3/2P switch was also taken into account. We have made an additional version of this switch that allows you to control two devices: one with the new Zenitco connector and the other with the previous connector. In total, there are currently three versions of the KV-D3/2P:

• Version 1.0 (not marked on the switch): the previous type of connector is used.
• Version 1.1: one connector of the previous version, the second is the new one.
• Version 2.0: uses the new Zenitco connectors.

The version can be selected on the product page in the "kit type" section.
To avoid confusion with the versions of compatible products, we publish a compatibility table. For example, if you have a Kleshch-2 flashlight version 2.0, which you want to control simultaneously with the Perst-4 version 4.0, then you need the KV-D3/2P switch version 1.1. And if Kleshch-2 is version 2.1, then the KV-D3/2P switch version 2.0 is required.

KV-D3/2P V1.1 combines Klesch-2 V2.0 and Perst-4 V4.0
