1.1 These conditions are valid exclusively between SWITEK and the Customer in connection with our delivery of goods and other services (referred to collectively as 'deliveries'). The supplier accepts the validity of these conditions for this and future business by agreeing to the contract.
1.2 These conditions remain valid in the event that we unconditionally make deliveries and/or accept payments without objection in knowledge of contradictory terms and conditions of the Customer. Discrepancies from our terms and conditions or the business terms of the Customer are thereby ineffective and will not become a constituent part of the contract except if they are recognised wholly or partially by us in writing.
1.3 The congruent mutual written declarations apply for the scope of deliveries. The validity of oral auxiliary agreements requires our written confirmation.
